Q:What Size Solar Panel Would I Need?
Solar in Chicago is not much help, you would need at least 3kwh for whatever size unit you have, (3 tons is meaningless in this context!) You would not get enough sun even in the summer to operate for more thn 6 hours a day. For Chicago you probably need a wind generator, or go for a heat pump.
Q:Solar Energy - What would these solar panels power?
For okorder.com As for that kit you are looking at, that is more suitable for mounting on a travel trailer somewhere where you are camping to recharge the deep cycle battery for the low voltage appliances you are using. Right now is probably a good time to start looking at ways of either running on low voltage, say for general lighting in a basement, or shed, and putting up some means of maintaining those batteries with solar and or wind. If you start small, you can add on at any time.
Q:are solar panels worth buying?
There are different kinds of solar panels. The biggest division is between photovoltaic panels that produce electricity and thermal solar panels that produce heat for hot water and space heating. Commercial photovoltaic panels are from 8 to 24% efficient while solar thermal panels are from 60 to 80% efficient. Solar thermal panels especially for hot water have a much higher ROI (return on investment) than photovoltaic panels. A solar hot water system may have a payback period (when savings equal the investment) as short as 3 to 5 years while photovoltaic panels will typically have a payback period between 7 and 5 years. Solar panels especially in times of low interest rates may be a very worthwhile investment with a better return than you can find almost anywhere else. But they are also highly dependent upon your situation. Owning a home with a good southern exposure is a prerequisite.
Q:Calculate solar panel energy output question?
A watt is the fee at which vigour is produced. It's analogous with horsepower, hp = 745W= 33,000 toes-lbs per minute. So the wattage of a sunlight panel is the capacity of the panel to drive a procedure like run a motor or power a radio. General energy calculations are a part of the bigger class of Physics.
Q:How many solar panels have ah?
But in reality, the need for solar panel power and solar charger to find a balance in the portability. It is generally believed that the minimum power of the solar charger can not be less than 0.75w, and the secondary power solar panel produces 140mA of current under standard light. In the general sunlight generated by the current at 100mA or so, if less than the secondary power charging current is too small,
Q:How much should a 00 watt solar panel cost?
On OKorder, they seem to be priced around $400. You do realize it takes more than just the panels...
Q:I want to buy solar panels?
If okorder.com and search for solar panels, they list companies that sell solar panels and you can compare prices there.

Q:solar panel help needed ?
You need to know how many solar cells are in the panel and what is the rated current each cell will produce. This information should be listed on the panel. Each cell will produce from 0.5 to 0.55 volts DC per cell and each cell will produce a current that is dependent on the size of the cell and the type of material the cell is made from. If the cells are connected in series then the voltage of each cell will add together, that is if you have 30 cells connected in series they should generate about 5 to 6.5 volts DC. If each cell generates .2 amps, then you multiply the voltage of 5 volts DC times .2 amps DC equals 8 watts of power. The current of each cell does not add together when you connect the cells in series only the voltage of each cell. If you connect the 30 cells in parallel then the current of each cell adds together but the voltage of each cell does not. That is 0.5 Volts DC times 36 amps equals 8 watts. The power (watts) produced will be the same. See our blog on the products page to see how to connect solar cells in series and in parallel. We also have a PDF file of solar cells and their rated output current sorted by watts per area and their manufacturer.
Q:Were solar panels made by copying how plants collect sunlight?
Not at all. Good guess but they are completely different processes. Solar panels use chemicals that create electricity when exposed to light. Photons pretty much add energy to the atoms and affect the electrons creating electricity. Feel free to look up how solar cells work online.
